Answer:

12,5 centimeters.

Step-by-step explanation:

We take the following proportion

[tex]\frac{1 cm}{80m} = \frac{x}{1000m}[/tex]

Which becomes:

[tex]1000 = 80x[/tex]

And then, we clear out the variable x:

[tex]\frac{1000}{80}=\frac{100}{8}=\frac{50}{4}=12,5[/tex]

And this means that the width of the lake on the scale drawing will be 12.5 cm.

Answer:

a= c+16

a-c= 16

Step-by-step explanation:

a = b + 12

b = c + 4

adding both eq.s, we get:

a+b = b+c+12+4

a+b = b+c+16

a = c+16

a-c = 16

Answer:

Step-by-step explanation:

From the information being provided;

We learnt that Becky pays simple interest at an annual interest rate of 8.8% which is calculated quarterly.

i.e. [tex]\dfrac{8.8\%}{4}= 2.2\%[/tex]

Since the first payment of $27,000 happened in the first three months, therefore, Becky will be able to have the money in the bank for 3 quarters prior to the lump-sum payment gets started.

Thus, the estimate of the amount Becky would earn as interest during this period of time is as follows:

[tex]I =\dfrac{PRT}{100}[/tex]

[tex]I =\dfrac{27000\times 2.2 \times 3}{100}[/tex]

[tex]I =\dfrac{178200}{100}[/tex]

I = $1,782

Complete Question:

Jamie used the distributive property to find the product of s(t) and h(t). His work was marked incorrect. Identify Jamie's mistake. What advice would you give Jamie to avoid this mistake in the future?

s(t)•h(t)= (3x-4)(2x-8)

= 6x² - 24x -8x - 32

= 6x² - 32x - 32

Answer:

Jamie made a mistake in his second line (6x² - 24x -8x - 32), by wrongly multiplying the operation signs. The last term should be +32, not -32.

Advice: Jamie should take note of the rule that applies when multiplying signs.

Step-by-step Explanation::

To find out where exactly Jamie made mistake, let's find the product of the given functions, step by step:

s(t)•h(t)= (3x-4)(2x-8)

Using distributive property, do the following:

[tex] 3x(2x - 8) -4(2x - 8) [/tex]

[tex] 3x*2x -3x*8 -4*2x -4*-8 [/tex]

[tex] 6x^2 - 24x - 8x + 32 [/tex] (this is where Jamie made mistake. -4 * -8 = +32. NOT -32.)

Add like terms

[tex] 6x^2 - 32x + 32 [/tex]

Jamie made a mistake in multiplying negative × negative. The last term in "6x² - 24x -8x - 32", should be +32. Negative × negative = +.

Therefore, it is advisable for Jamie to always take note of the rule that applies when multiplying signs.

Answer:

The correct answer is x =55°

Answer: 14 pieces

Step-by-step explanation:

Let the number of pieces of paper she had at first be x.

Before starting she got seven more pieces to use. This can be written as:

= x + 7

When she was done she had 28 half pieces of paper. This can then be written as:

x + 7 = (28 × 1/2)

x + 7 = 14

x = 14 - 7

x = 7

Since x = 7, she started with:

= x + 7

= 7 + 7

= 14 pieces

Answer:

The correct answer is:

Sydney should choose the median after dropping one test score.

Step-by-step explanation:

when scores are not dropped:

List of scores = 68%, 84%, 94%, 100%

Mean = (68 + 84 + 94 + 100) ÷ 4 = 86.5%

Median = 68  84  94  100

Median = (84 + 94) ÷ 2 = 89%

Although there are no outliers because Sydney was given the option to drop a test score, dropping the lowest score will increase his overall chances of making a higher score. Therefore, 68% will be dropped.

List of scores when the lowest score is dropped  = 94%, 84%, 100%

Mean: (84 + 94 + 100) ÷ 3 = 92.7%

Median: 84, 94, 100

Median = 94% (middle term)

From  the four possible scores, the highest score is 94%, and it is gotten by finding the median after dropping a score

Answer:

$4000

Step-by-step explanation:

use formula a = w*p

1200.00 = w0.3

/ 0.3          /0.3

w = 4000

The total earnings done by Jackson last month will be equal to 4000.

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given information provided in the question,

Total investment is done by Jackson = 1200

The investment is 30% of total earnings.

Assume that Jackson's earnings are x.

Then,

30% of x = 1200

x = 1200 × (100/30)

x = 4000
